ORE-WASH ER.

SPECIFICATION forming part of Letters Patent No. 265,766, dated October10, 1882.

Application filed September 24, 1881.

To all whom it may concern:

Be it known that I, ALONZO MESIA DE LA GERDA, a citizen of Spain,residing at Madrid, in the'Kingdom ofSpain, have invented a new anduseful Improvement in Ore VVashers, (for which I have obtained a patentin Spain, dated May 19, 1879, No. 184,) of which the following is aspecification.

This invention consists in an ore-washer wherein are combinedalongitudinally-inclined cradle having two openings at the lower endthereof-one next to the bottom for discharging the ore and the otherabove the bottom for discharging the sand and water-either or bothopenings being adapted to be closed at will, a fixed shaft extendinglongitudinally through the cradle and having the latter arranged to rockthereon, and ore-agitators fixed to the cradle and shaft, respectively,to 00-01)- crate with each other; also,in the combination, with theforegoing, of a. bifurcated hopper whiclrextends into the cradle, attheupper end thereof, and straddles the shaft, bringing the delivery endof the hopper below it.

This invention is illustrated in the accompanying drawings, inwhichFigure 1 represents an end view. Fig. 2 is a side elevation. Fig. 3 is avertical longitudnal section. Fig. etis a vertical cross-section. Fig. 5is a plan or top view. Fig. 6 illustrates details ofconstruction.

Similar letters indicate corresponding parts.

The letter A designates the cradle; 13, the shaft; E G, theore-agitators, and L the hopper.

The cradle A has an approximately semicylindrical shape, and the flattop is hinged and locked to the round bottom or body thereof forconvenient accessto itsinterior, the whole being inclinedlongitudinally. At the lower end of the cradle A are two openings, IJ,one of which is immediately next to the bottom or shallow part thereof,while the other is above such bottom, and either or both of which areadapted to be closed by suitable covers. (Not shown.)

The shaft B is polygonal at its opposite ends, where it restsin bearingsI), applied to a suitable frame, so that it occupies a fixed position,and the shaft extends longitudinally through the cradle above its centerof gravity, while those portions of the shaft at or opposite the ends ofthe cradle are rounded, the cradle being provided with bearings Otherefor, whereby the cradle is adapted to rock on the shaft. This shaftB is placed in an inclined position for the purpose of bringing thecradle into the desired plane.

The agitators E are fixed to the shaft B, as by means of set-screws 0,and consist of segmental spiders terminating near the bottom of thecradle A, and having laterally-projecting spurs F.

The agitators Gare fixed to the cradle A by bolts or other suitablemeans, and alternate with the agitators E,\vhile they are composed, likethe latter, of segmental spiders having laterally-projecting spurs H,which are between those of the agitators E, allowing the agitators topass and repass each other.

The hopper L extends into the cradle A, at the upper end thereof,through a suitable opening, and it is bifurcated at the lower end, asindicated in Fig. 4, to straddle the shaftB, so that the delivery end ofthe hopper is brought below the shaft and near the bottom of the cradle.

In the upper part of the hopper N is a riddle, M, which is removable,being provided with suitable handles.

In applying the apparatus to use the opening J is closed and the ore isintroduced into the hopper L, together with a suitable quantity ofwater, thence passing into the cradle A, while at the same time arocking motion is imparted to the cradle, so that as the ore descends onthe bottom thereof by its inherent gravity it is subjected to the actionof the agitators E G, In this manner the ore is divided and washed, andthe heavy or metallic particles are allowed to collect on the bottom ofthe cradle at or upward from its lower end,while the water overflowsthrough the upper opening, I, carrying with it the sand or earth.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbefore described, of thelongitudinally-iuclined cradle having two openings at the lower end'thereof -one next to the bottom for discharging the ore and the otherabove the bottom for discharging the sand and Water--thefixed shaftextending longitudinally through the cradle ICC the ore-agitators fixedto the cradle and shaft, respectively, and the bifurcated hopperextending into the cradle, at the upper end thereof, and straddling theshaft.

- In testimony whereofI have hereunto set my hand in the presence of twosubscribing Witnesses.

and having the latter arranged to rock thereon, and the ore-agitatorsfixed to the cradle and shaft, respectively.

2. The combination, substantially as hereinbei'ore set fortln of thelongitudinally-inclined cradle having two openings at the lower endthereof-one nextto the bottom for discharging the ore and the otherabove the bottom for I discharging thesand and water-thefixed shaftextending longitudinally through the cradle and having the latterarranged to rock thereon,
